PEMANFAATAN LIMBAH SEA WATER DAN ENGINE OIL PADA INDUSTRI PETROKIMIA UNTUK PROSES QUENCHING PADA BAJA S45C

Introduction

Pemanfaatan limbah sea water dan engine oil pada industri petrokimia untuk proses quenching pada baja s45c. Pemanfaatan limbah sea water dan engine oil petrokimia untuk quenching baja S45C. Studi ini tingkatkan kekerasan material, limbah sea water lebih efektif. Dukung industri berkelanjutan.

Abstract

Studi tentang penggunaan baja karbon S45C pada industri manufaktur telah mengalami perkembangan yang peesat. Tidak hanya pemanfaatan pada komponen dan peralatan industri, namun upaya peningkatan sifat material melalui berbagai metode termasuk perlakuan panas juga semakin menarik bagi para peneliti. Penelitian tentang media quenching air laut (sea water) dan engine oil menjadi salah satu pilihan bagaimana peningkatan kekerasan material pada baja karbon S45C. Namun studi tentang pemanfaatan media quenching sea water dan engine oil dari limbah industri Petrokimia belum banyak dilakukan. Pada penelitian ini perngaruh media quenching berupa limbah sea water dan engine oil terhadap perubahan kekerasan material pada baja karbon S45C. Dari hasil pengujian yang dilakukan didapatkan penggunaan media sea water dalam proses quenching memberikan hasil nilai kekerasan yang lebih tinggi yaitu sebesar HVN 754,10 pada bagian tepi material dibandingkan dengan media quenching engine oil yang memiliki kekerasan tepi sebesar HVN 320,97. Pemanfaatan limbah pada industri petrokimia ini mendukung penerapan industri yang lebih berkelanjutan

Review

This study presents an intriguing investigation into the utilization of waste materials from the petrochemical industry for the heat treatment of S45C carbon steel. Specifically, the research explores the efficacy of spent seawater and used engine oil, sourced as industrial waste, as quenching media. The premise addresses a critical need for sustainable manufacturing practices, aiming to valorize industrial by-products while enhancing the properties of widely used engineering materials. This innovative approach contributes significantly to the circular economy by repurposing challenging waste streams for a valuable industrial process like quenching. The core of the methodology revolves around evaluating the impact of these waste media on the hardness of S45C steel. The abstract reports a direct comparison between waste seawater and waste engine oil in the quenching process. A key finding indicates that quenching with waste seawater yielded a considerably higher hardness value of HVN 754.10 at the material's edge. In stark contrast, quenching with waste engine oil resulted in a significantly lower edge hardness of HVN 320.97. These quantitative results demonstrate a clear differential effect, highlighting waste seawater as a potent quenching medium capable of imparting substantial hardening to S45C steel. The strength of this research lies in its strong practical relevance and direct contribution to industrial sustainability. By demonstrating the effective utilization of petrochemical waste for a critical manufacturing process, the study provides a compelling case for resource efficiency and waste reduction. While the abstract focuses primarily on hardness, the significant difference observed between the two waste media warrants further in-depth investigation into underlying microstructural changes and the long-term performance implications. This work serves as an important foundation for promoting more sustainable practices in both the petrochemical and metal processing industries, suggesting promising avenues for valorizing other industrial waste streams in similar applications.
